TO ALL WHOM IT MAY CONCERN:

Be it known that I, VINCENT M. BAKER, of Preston, in the county ofFillmore, and State of Minnesota have invented a new and improvedWater-Wheel; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification. n

` This invention relates to a new and improved water-wheel, of thatclass which are placed on a vertical shaft, and are commonly termedhorizontal wheels.

The invention consists in a novel arrangement of chutes and gates forregulating the supply of water to the wheel.

In the accompanying sheet of drawings- Figure 1, Sh'eeLNo. I, is avertical central section of my invention, taken in the line :1; x, iig.2.

Figure 2, a horizontal section of the same, taken in the line y y, iig.1.

Figure 3, Sheet No. 2, a vertical section of the same, taken in the linez z, tig. 2.

Figure 4, a detached inverted plan of the wheel.

Similar letters of reference indicate corresponding parts.

A represents a cylindrical curb, in which the wheel B is fitted andworks.

C being the shaft of the wheel, thelower end of which is concave, andworks on a conical point or step, a, on a block, D, which is fitted in asocket, E, attached to a cross-piece, b, which is secured to the lowerpart of the curb. v

This b lock D rests on a wedge-shaped or taper bar, F, which is placedon the cross-piece b, and fitted between guides or side-pieces c c, atthe edges thereof, and, by adjusting this bar F, the wheel B 'may beraised or lowered to the required height;

This will be fully understood by referring to fig. 1.

The bar F may be operated by meansof a handle, al, and retained in.place by a wedge, e, tted within a vertical box, eX, (see tig. 1.) l

The wheel B is composed of a central curved plate,f, having a concaveouter surface, as shown clearly in g. 1, and another similar curvedplate, g, placed midway betweenf and a low or narrow'plate, le, at thelower exterior part of the wheel.

y The buckets z' extend from the top of platef down to'the bottom of thesame, their upper parts down to the top' of plate y having a radialposition, and from thence downward a curved form, as shown clearly iniig. -3, the plate g 'dividing the buckets, the upper radial parts fromthe lower curved parts.

By this construction and arrangement of the buckets, the direct power ofthe water is obtained, and also the reacting power, or that due toweight or gravity; the first being obtained by the watercoming incontact with the upper radial parts of the buckets, and the latter bythe water passing down over the lower curved parts of the buckets,l thewater being discharged from the bottoms of the buckets, in consequenceof the plate or rim 7L at the lower exterior part ofthe wheel.

The upper part of the'wheel is enclosed by a series of chutes, zx, (seemore particularly g. 2,) and in each chute there is a sliding gate, G.

These gates are fitted, oneagainst each partition j,which formthechutes, and the inner end :of the gate of one partitionj worksbetweenthe inner end of the partition directlyin front of it and theexterior of the wheel, and consequently it will be seen that byoperating the gates, drawing them in and out, more or less water may beadmitted to tlie wheel, as desired, and in such a direction as to strikethe upper radial parts of the buckets at right angles, the positionofthe gates and chutes being such as to effect thatresult.

The gates G are' attached to a. ring, H, which is fitted within asuitable annular guide, I,has a number of teeth, lc, attached, intowhich a pinion, Z, gears, the latter being on a vertical shaft, m,provided with a crank, n, on its upper end.

By turning this shaft fm, the ring H may be turned, and -the gates Gmoved in or ont with the greatest facility, and the precise amount ofwater required let upon the wheel, without any trouble or difficultywhatever.

I claim as new, and desire to secure by Letters -Patent- The chutes z'X,in combination with the sliding gates G, operated through the medium ofthe ring H and gearing lc Z, all arranged substantially as and for thepurpose set forth.

The above Aspeeifcation of my invention signed by me, this 8th day ofJanuary,`1868.

` 'VINCENT M. BAKER.
